Great video, I have a Seagull Acoustic and a La Patrie Classical, both from the same factory. They are well made guitars.
The videos I like are the ones where the little old Oriental guys are making guitars by hand, and do a lot of these steps by hand. They have subtitles , but show you the craftsmanship at a whole new level. They explain why they pick out certain pieces of wood for this or that, and how humidity plays a part of the decision. There is an art to bracing the inside just right for sound. Some of these videos are an hour or two long, but well worth it.
Thanks for sharing, good thread. Jim
